The present invention relates generally to electronic smoking devices and in particular electronic cigarettes. A mouthpiece for an electronic smoking device has an elongated housing having ports at opposite ends; a central passage formed as a hollow channel through the housing in communication with the ports, contact terminals for connecting to a battery of the electronic smoking device and conductive elements connected to the contact terminals, the conductive elements being configured for connecting, to the battery, an tempering element for tempering an aerosol produced by the electronic smoking device. Using the tempering element, aerosol passing through the central passage can be tempered and loss of aerosol due to condensation is reduced.

The embodiments herein provide a filter for cigarette comprising graphene nano-composite based material enclosed in a casing. The filter is reusable and is plugged to any cigarette, or tobacco smoking products. The filter is a stand-alone product or manufactured integrally with each individual cigarette. The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke. The graphene based nanocomposite filter adsorbs the toxic agents from the smoke (of cigarette, beedi, hookah etc). The filter is fabricated by treating ceramic particles and coating them with carbon particles. The carbon particles are carbonized. The ceramic particles coated with carbon are segregated based on shape and size and treated chemically to convert carbon into graphene under inert conditions. The graphene coated particles are chemically functionalized for improved filtration.

A capsule (120) for use in a smoking article includes a liquid sensory enhancing material; and a shell surrounding the liquid sensory enhancing material. The shell has an outer surface rendered hydrophobic by hydrophobic groups covalently bond to the outer surface of the shell. The shell may be rendered hydrophobic by reacting hydroxyl groups at outer surface of the shell with fatty acid halides to covalently attach fatty acid moieties to the surface of the capsule.

The present disclosure provides, in one embodiment, a filter device comprising a mouthpiece, a filter assembly in communication with the mouthpiece for filtering air exhaled into the mouthpiece, and an outlet check valve which permits air to be exhaled through the mouthpiece into the filter assembly, and substantially prohibits air from being inhaled from the filter assembly into the mouthpiece.

A cartridge for an electronic smoking device includes a heat source comprising a bulb-encased heating element. The heat source is disposed inside a compartment of the cartridge. The compartment extends from an air flow tube. The housing includes a storage area for retaining inhalant material. The cartridge includes a threaded connector that attaches to a control unit that has a power supply such as a batter. The cartridge avoids direct contact between the inhalant material and any metal components of the cartridge by either eliminating metal components or by encasing the metal components in glass, quartz, or ceramic.
